The Suns defender was suspended for three games last year after colliding with Lions captain Tom Rockliff.

This means May has an applicable bad record that would increase any suspension by one game.

AFL.com.au's Tribunal expert Nathan Schmook expects May to receive the most severe penalty to date this season, eclipsing the four-game ban handed to GWS forward Jeremy Cameron for his late hit on young Lion Rhys Mathieson in the NAB Challenge.
